The Savi's warbler (''Locustella luscinioides'') is a species of Old World warbler in the grass warbler genus ''Locustella''. It breeds in southern Europe and temperate western Asia. It is migratory, wintering in northern and sub-Saharan Africa. This small passerine bird is found in reed beds, usually with some bushes. Three to six eggs are laid in a nest in reeds. The adult has an unstreaked grey-brown back, whitish grey underparts and a lack of throat streaks, which is a distinction from the river warbler. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. This is not a shy species, but can be difficult to see in the reeds except sometimes when singing. The is a monotonous mechanical insect-like reeling, often given at dusk. It is similar to the song of other species in the group, but is generally faster and deeper and bears a strong resemblance to that of Roesel's Bush-cricket. ==Taxonomy== The common name of this bird recognises the Italian ornithologist Paolo Savi, the author of "Ornitologia Toscana" (1827–1831) and "Ornitologia Italiana" (1873–1876). In 1821, Savi was given specimens of an unstreaked, dark, rufous-brown warbler which was new to science. He published a full description of the bird in 1824, and it became known by the common name of Savi's warbler. It forms a species pair with ''Locustella fluviatilis'' and studies of mitochondrial DNA show that both are closely related to ''Locustella lanceolata'' and the ''Locustella naevia''.〔(【引用サイトリンク】title=Savi's Warbler (''Locustella luscinioides'') )〕 There are three subspecies. ''Locustella luscinioides luscinioides'' is the nominate subspecies which is native to Central and Eastern Europe, Spain, Portugal and North Africa. It winters in West Africa in an area stretching from Senegal to Lake Chad and northern Ghana, and probably also in South Sudan.〔 ''Locustella luscinioides sarmatica'' is native to Ukraine, the Sea of Azov, the Volga region and the Urals; it winters in North Eastern Africa. ''Locustella luscinioides fusca'' is found from Jordan and Turkey as far east as central Asia; it winters in Sudan and Ethiopia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Savi's warbler」の詳細全文を読む スポンサード リンク
